Explanation

To determine the correct order of strength of hydrogen bonding in the given compounds, we will analyze the electronegativity of the atoms involved and the structure of each compound.

### Step-by-Step Solution:

1. **Understand Hydrogen Bonding**:
- Hydrogen bonding occurs when hydrogen is bonded to a highly electronegative atom (like F, O, or N). The strength of hydrogen bonding is directly proportional to the electronegativity of the atom to which hydrogen is bonded.

2. **Identify the Compounds**:
- The compounds we are comparing are HF (Hydrogen Fluoride), H2O (Water), H2O2 (Hydrogen Peroxide), and H2S (Hydrogen Sulfide).

3. **Evaluate Electronegativity**:
- The electronegativities of the relevant atoms are as follows:
- Fluorine (F): Highest electronegativity
- Oxygen (O): Moderate electronegativity
- Sulfur (S): Lowest electronegativity
- Therefore, the order of electronegativity is: F > O > S.

4. **Analyze Each Compound**:
- **HF**: The hydrogen bond is very strong because fluorine has the highest electronegativity.
- **H2O**: Water has strong hydrogen bonds due to the presence of oxygen, which is also highly electronegative.
- **H2O2**: Hydrogen peroxide has weaker hydrogen bonds compared to water because it has a lower effective electronegativity due to the presence of an additional oxygen atom which reduces the overall electronegativity effect.
- **H2S**: Hydrogen sulfide has the weakest hydrogen bonds because sulfur is the least electronegative of the atoms involved.

5. **Rank the Compounds**:
- Based on the above analysis, we can rank the compounds in order of hydrogen bonding strength:
- 1st: HF (strongest)
- 2nd: H2O
- 3rd: H2O2
- 4th: H2S (weakest)

6. **Final Order**:
- The correct order of strength of hydrogen bonding in the compounds is:
- HF > H2O > H2O2 > H2S
